Specification of Letters Patent.

Patented Mar. 17?, 1914- Application filcd May 12, 1913. Serial No.767,102.

To all whom it may concern Be it known that I, Josnrn WV. Romans, acitizen of the United States, residing in l/Voodbury, county ofGloucester, and State of New Jersey, have invented certain Improvementsin Insulating and Supporting Mechanism, of which the following is aspecification.

My invention relates to insulating sup ports for third rails of electricroads, and its primary object is to provide a simple, compact ande'ilicient construction that will permit the use of narrower ties orbearings than have heretofore been required.

In the usual practice of the prior art it has been customary to use aninsulating support for the rail and a support for the protecting boardplaced side by side upon the tie, which necessitates the use of ties ofconsiderable width, as well as sound ends of considerable breadth.

It is a desideratum to have a construction which permits the use of tiesof moderate width and ends which may not be wholly sound or of fullwidth. This is accomplished by my invention in which the insulatingsupport for the rail fits over the base of the support for theprotecting board, and in the preferred construction such supports have acommon median plane approximately coincident with the screws by whichthe said base is fixed to the tie.

In the accompanying drawings, Figure 1 is a transverse verticalsectional view of part of a track having my improvements appliedthereto; Fig. 2 is an elevation of a section of said track at rightangles to that shown in Fig. 1; and Fig. 3 is a bottom View of theinsulating support.

The mechanism, as illustrated in the drawings, comprises the tie 1, therail 2 for carrying the rolling stock, the third rail 3 for carrying thecurrent, the insulator I which bears upon the tie and carries the rail3, and the supporting strut 5 having the base 6 which is fixed upon thetie by the lag screws 7 and the top arm 8 to which is fixed theprotecting board 9 by the bolts 10.

The insulator 4; is provided with the top seat 11 for the rail 3, thecentral bottom channel 12 which fits over the base 6, the recesses 13which fit over the heads of the lag screws 7, and the channels 14: whichextend transversely to the channel 12 to facilitate evaporation andsecure ventilation.

This construction thus brings the base of the protecting board supportwithin the sides of the insulator and permits such support and insulatorto be placed upon a comparatively narrow tie or narrow part of a tie, sothat a narrow tie or a tie with a defective or only partially sound endmay be used, which would not be practicable with the former constructionhaving the base of the protecting board support placed at the side ofthe insulator.

Having described my invention, I claim:

1. In an insulating and supporting mechanism, an insulator having a seatadapted for supporting a rail and a bottom channel extendingtransversely to said seat from side to side 01 said insulator.

2. In an insulating and supporting mechanism, an insulator having a seatin the top thereof and a channel in the bottom thereof, said channelhaving terminal recesses.

3. In an insulating and supporting mcchanism, the combination with atie, oi. an in sulator having a bottom channel extending longitudinallyof said tie and a supporting device having a base resting on said tiewithin said channel.

4. An insulating and supporting device comprising a top seat, a channelextending transversely thereto, said channel having terminalenlargements, and bottom channels extending transversely to said channelfirst named.

5. The combination with a tie, a rail and a protecting device for saidrail, of a protecting device support having a base extendinglongitudinally of said tie, lag
